First Flight #1: PasswordStore

Summary

The code defines an event SetNetPassword() to log password changes, but it lacks additional parameters to provide context and information about the password change event. By including parameters like address indexed user and string newPassword in the event, the event logs can become more informative and useful.

Vulnerability Details

The code defines the event SetNetPassword() as follows:

However, this event does not provide any additional information about who changed the password or what the new password is. As a result, it lacks context, which can be helpful for debugging and monitoring contract activities.

Impact

The absence of event parameters in the SetNetPassword event does not pose a security vulnerability but impacts the contract's usability and transparency. The event's logs are less informative, making it harder to track changes to the password.

Tools Used

No specific tools are used for this analysis. It's a manual code review based on the provided code snippet.

Recommendations

To improve the contract's transparency and monitoring capabilities, it's recommended to include event parameters that provide context and information about password changes. Here's an example of how you can modify the event:

With this modification, you can emit the event as follows:

Now, when a password change occurs, the event logs will include the address of the user who changed the password and the new password, which can be valuable for monitoring and analysis.
